Lens driving device, camera module, and camera-mounted apparatus

A lens driving device that applies a force to the liquid lens to change a focal length and an optical axis of the liquid lens, the lens driving device comprising:

• a fixed part;
• a movable part disposed apart from the fixed part;
• a first elastic support member and a second elastic support member that elastically connect the movable part and the fixed part to each other and supports the movable part with respect to the fixed part;
• a driving part including a voice coil motor that includes a coil and a magnet, the driving part being for moving the movable part with respect to the fixed part in a direction of the optical axis;
• and
• a lens deforming part connected to the movable part, the lens deforming part being for applying a force to the liquid lens in the direction of the optical axis in accordance with a movement of the movable part, wherein:
• the movable part includes a plurality of movable units,
• the coil is disposed in each of the plurality of movable units,
• the magnet is disposed at each of positions in the fixed part, the positions corresponding to the plurality of movable units,
• the plurality of movable units each includes a control Integrated Circuit (IC) that controls energization of the coil,
• the first elastic support member is electrically connected to a wiring disposed at the fixed part and a power supply terminal of the control IC, and connects the power supply terminals in adjacent movable units of the plurality of movable units to each other,
• the second elastic support member is electrically connected to a wiring disposed at the fixed part and a signal terminal of the control IC, and connects the signal terminals in the adjacent movable units to each other, and
• the driving part drives the plurality of movable units independently in such a way that a curvature of the liquid lens changes or the optical axis of the liquid lens changes.
